ODB — who’s been dead since November 2004 — appeared alongside his Wu-Tang Clan brethren for performances of “Shame on a Nigga” and “Shimmy Shimmy Ya”, which also featured his son Young Dirty Bastard. You can watch fan footage of the whole thing below.

As MTV reports, the Eazy-E and ODB holograms were created by director Chris “Broadway” Romero with help from AV Concepts, who was also behind the Tupac hologram at Coachella.

To recreate that feeling, Romero and a team of about 15 different people used a myriad of different reanimation techniques and even some motion capturing. “With Eazy-E, I actually worked with all of his kids,” he revealed. “One of his kids helped with the voice of Eazy-E talking to the crowd, one of his kids did his actual body movements and one of his kids did his facial movements.”

Broadway also was sure to include ODB’s son Young Dirty, who regularly performs with Wu-Tang in his dad’s place. “In terms of embodying his father, straight A-alike. There’s no one closer you’re going to get to bring that performance out,” he said. “There’s digital DNA infused into these projects and it’s the only way I like to work, as much as I can. I don’t like to coldly separate from stuff, especially if there is willing family involvement.”

The holograms don’t come without their risks, however. This is what was posted backstage (via Marcellacomedy):
